Do the above have "powers of arrest" anywhere in the UK as they are a National Police Force?
For example if a BTP officer was travelling on a train between Carlisle and Edinburgh could he arrest people either side of the border for offences committed on the train.
Just curious as the legal systems are different - are the "train laws" as it were the same?
It is an urban myth that officers cannot arrest outwith their own area, it is all about where the offence took place
If the offence took place in Carlisle and was arrested in Edinburgh, the matter is reported to the court in Carlisle; if an arrestable offence then would be returned to Carlisle
If an offender boards at Carlisle (northbound with next stop Edinburgh), then the offence will be referred to the court in that area
If an offender boards at Edinburgh (southbound next stop Carlisle), then the offence will be referred to the court in that area
If the offence takes place between Carlisle and Lancaster, such that the offender is removed at Lancaster, then the offence will be referred to the court in that area
The BTP officer will normally attend court
However, if there is no BTP officer then a local officer may attend court instead
I once had BTP officers attend at Dunbar, along with two local Scottish CID officers
They removed five passengers, and the matter was referred to the local court, the BTP officers did not attend court but were cited as witnesses
